Description

Crosstalk Reduced Modular Outlet

In general, conventional modular outlets also have the following limitations.

Many conventional modular outlets have IDC terminals serialized according to the wiring method of T568A or T568B of / 568. According to this IDC terminal sequence, it is necessary to untwist and divide a wire pair having a disadvantageous effect on crosstalk performance among twisted wire pairs.

Conventional modular outlets cannot be stacked side by side when installed in a panel. If a high outlet density is required, the above conventional configuration sacrifices space efficiency.

Conventional modular outlets must be installed into the panel opening from the rear of the panel. In practice, most users choose to install the terminal outlets from the front of the panel.

Many conventional outlets that use terminal caps require extensive cable preparation before being able to attach the cables to the bullet caps. In general, each twisted pair must be untwisted, and individual wires must also be stretched and aligned before being able to install the cable in the terminal cap and trimmed if necessary.

The disadvantage of the ITT Outlet is that it requires four discrete housing elements. Current hinge designs have limitations such as limited material selection and damage to mechanical integrity.

Known doors used for conventional outlets are generally spring-loaded, so that they do not remain in the open position but only in the closed position. Because of this, the user has to use both hands when installing the plug, and keep the door open with one hand and install the plug with the other hand.

TECHNICAL FIELD The present invention relates to connectors, and in particular, to connector assemblies for use primarily in telecommunication devices and similar devices.

The efficiency of the communication system and / or network is directly determined by the complete integrity of the connector configuration used, which includes standard interfaces for facility / user access (outlet connectors), communication means (horizontal). And backbone cabling), and management / distribution points (cross-connecting and patching facilities). Regardless of the type or capability of the transmission medium used in the installation, the integrity of the cabling infrastructure is the same as the performance of the individual elements coupled to each other.

For example, a non-standard connector or pair configuration might have installation transport features that exhibited poor performance due to group movement, system changes, or previously compatible but later extended or upgraded systems at higher rates. It may be necessary to reconfigure the wiring of the work area outlets in order to have the hardware with which it is connected. In particular, in the case of connecting hardware that does not have acceptable design and transmission capability, there may be a reduction in user productivity, a decrease in system performance, and significant limitations on new applications.

Reliability, complete integrity of the connection and durability must also be taken into consideration, since the cabling typically lasts 10 to 20 years. It is desirable to establish a meaningful and accessible reference point in order to properly check the details of the telecommunication connection hardware and its performance. International standards for commercial telecommunication devices and installations include the ANSI / TIA / EIA-568-A (/ 568) Commercial Building Telecommunications Cabling Standard and consumer cabling 150 / IEC 11801 (/ 11801). The characteristics of telecommunication cabling judged by these criteria include connection hardware design, reliability and transmission performance. Thus, in the industrial field, pass / fail criteria have been established that are the basis for a common set of test methods and performance requirements and comparative data.

To determine access hardware performance in a data environment, it is desirable to establish test methods and pass / fail criteria for a wide range of applications and various types of connectors. Since the relationship between megabits and megahertz is determined by the coding configuration used, the performance requirements for the wiring elements representing the transmission rate are meaningless without providing reference to industry standards or coding configurations. Therefore, both manufacturers and end users are interested in standardizing performance information over a wide range of applications. For this reason, in the case of coverage-independent criteria such as / 568 and / 11801, the performance criteria are specified in hertz rather than in bits. This information is used to determine whether the requirements for a particular application are compatible. For example, many performance requirements in IEEE, 802.3i (10BASE-T) are specified in megahertz, and in application, even if data is transmitted at 10 Mbps, the reference is test "frequency" (as high as 15 MHz). It is specified as. Transmission variables defined at / 568 and / 11801 for twisted pair connectors include attenuation, near-end crosstalk (NEXT), and feedback loss. The minimum effect on channel performance of these variables is expressed as signal noise ratio (SNR). In the case of access hardware, the variable known to have the maximum impact on the signal noise ratio is near-end crosstalk.

There are a number of established industry standards that specify different levels of performance for twisted-pay cabling elements, such as cables in categories 3, 4, and 5 in both / 568 and / 11801, and in other national and regional specifications. Connection hardware is specified. In these specifications, the transmission requirements for Category 3 devices are specified up to 16 MHz, the transmission requirements for Category 4 devices are specified up to 20 MHz, and the transmission requirements for Category 5 devices are 100 Specified up to MHz. The Category 5 classification defines the most stringent transmission requirements specified by national and international standards for unshielded and screened twisted pair cabling.

In order for a twisted pair connector to meet a given performance category, it must meet all applicable transmission requirements, regardless of design or intended use. Efforts to meet transmission criteria are cumbersome due to the fact that connector criteria are applied to worst case performance. For example, for all pair combinations except category 3, a work area outlet that meets category 5 NEXT requirements may only be classified as a category 3 connector (except for all other applicable requirements). Under matching conditions).

It should be noted that there are several ways to achieve an electrical balance for the connection hardware of the type according to the invention. Category 5 type outlet connectors are now commercially available. These connectors include Systemax SCS Category 5 from AT & T Network Systems, DVO Plus and BLX Plus from Nothern Telecom, and Category 5 ACO Outlet from AMP. This list is only an example and is not an exhaustive list of Category 5 products on the market. Thus, there is still a need for improved outlet connectors that meet or exceed Category 5 performance requirements to meet the increasing bandwidth requirements of communication systems and networks.

The Systemax SCS Category 5 Outlet manufactured by AT & T Network Systems uses "cross-over lines" to achieve the required level of crosstalk without the use of printed wiring boards or other additional devices (Denkman et al. US 5,186.647). It uses a variation of the well-known leadframe outlet structure that has been used by many companies for years. Although this method provides a potential cost advantage by minimizing the amount and form of elements in the finished assembly, there are limitations in many respects.

Another equilibrium compensation method is, for example, a method of selectively extending circuit traces in parallel within a parallel configuration of traces which are positioned in an overlapping state on adjacent layers of the circuit board. It is also possible to vary the thickness of the trace to achieve inductive balance correction between pairs. Another method is to place a portion of the flexible printed circuit (FPC) on the top surface of the contact array. Selected contacts are electrically connected to portions of the flexible printed circuit. Some of these methods are described in US Pat. No. 5,299,956 to Brownell. Another way to balance the pairs without using leadframe or printed circuit configurations is to selectively twist the wires exiting behind the conventional modular outlets. However, these methods all have inherent limitations in terms of repeatability, cost and performance. For example, a design in which a passive flexible printed circuit is installed on a lead frame has disadvantages such as resonance crosstalk. When using twisted wires, there is a problem in that they are inconsistent and expensive.

The modular outlet manufactured by ITT Cannon, having a crosstalk reduction characteristic, has a connector housing accommodating a contact carrier for supporting a plurality of contacts therein. The housing is hingedly coupled with a terminal cover for connecting a plurality of wires to one end of the contacts. The T568A pin / pair method specified in Criteria / 568 is used, in which case the R4 contact includes an insulator moving terminal connected to the modular outlet terminal by a plate. The T4 contact includes an insulator moving terminal connected to the modular outlet terminal by a line. The T1 contact includes an insulator moving terminal connected to the modular outlet terminal by a plate. The R1 contact includes an insulator moving terminal connected to the modular outerlet terminal by a plate. The R3 contact includes an insulator moving terminal connected to the modular outerlet terminal by a line. The T3 contact includes an insulator moving terminal connected to the modular outlet terminal by a plate. The R2 contact includes an insulator moving terminal connected to the modular outerlet terminal by a first line. The second line of the R2 contact extends from one side of the first lead of the R2 contact to the first plate of the R2 contact. The third line of the R2 contact extends from the other side of the first lead of the R2 contact to the second plate of the R2 contact. The T2 contact includes an insulator moving terminal connected to the modular outerlet terminal by its first line. The second line of the T2 contact extends from one side of the first lead of the T2 contact to the first plate of the T2 contact. The third line of the T2 contact extends from the other side of the first lead of the T2 contact to the second plate of the T2 contact.

The plate of the R4 contact is located oppositely on the second plate of the R2 contact, the plate of the R1 contact is located oppositely on the first plate of the R2 contact, and a dielectric plate is located between the opposing plates. Thus, a capacitive coupling is induced or added between the R2 contact and the R4 and R1 contacts. The plate of the T1 contact is located oppositely on the second plate of the T2 contact, the plate of the T3 contact is located oppositely on the first plate of the T2 contact, and the dielectric plate is located between the opposing plates. Thus, capacitive coupling is induced or added between the T2 contacts and the T1 and T3 contacts.

It should be noted that the plates are shunts connected to the signal carrier to allow passage of signals from the signal input to the signal output while preventing the passage of current. These passive capacitive plates have known problems such as resonance crosstalk and phenomena due to signal reflection and / or lack of signal balance.

The above and other problems of the prior art are overcome or alleviated by the modular outlet with crosstalk reduction characteristics according to the present invention. The present invention makes it possible to stack the outlets closely and side by side, thereby enabling an increase in the outlet density and space efficiency. According to the present invention, the contacts are configured to sequentially arrange the IDC terminals, so that there is no split among the twisted wire pairs. Moreover, the outlets of the present invention can be installed in IEC 603-7 industrial-standard panel openings and have a wider range of applications. An important feature of the present invention is that installation in both front and rear directions is possible. The modular outerlet according to the present invention includes a connector housing in which a contact carrier for supporting a plurality of contacts is accommodated therein. The housing is coupled with a terminal cap for connecting a plurality of wires to one end of the contact.

The connector housing, as is well known, includes a front panel with a standard contact opening formed therein, such as an 8-position or 6-position modular outlet opening. From this front panel, a side panel, an upper panel, and a lower panel extend. From the upper panel, an upright part which cooperates with each other extends, and a retention protrusion is formed at an end thereof to form a slot for accommodating an icon or an insert. In addition, the inclined upright portion and the inclined surface are formed in the upper panel, and the panel accommodation slot which extends to an opening is formed. From the rear of the lower panel, the elastic panel extends along the contour of the lower panel. The panel accommodating slot is formed also in the front end part of this elastic panel.

The contact carrier includes a generally L-shaped front member that fits a standard modular plug, which has a plurality of slots therein for receiving contacts therein. Slots are formed in an arcuate recess formed in the front end of the lower leg of the front member. The contact carrier is inserted into the connector housing. The terminal block portion extends rearward from the lower end of the upper leg portion, and a plurality of slots are formed in the lower portion of the terminal block portion for accommodating the contacts. Each slot is connected to an opening extending through the block portion, through which the corresponding contacts pass. According to one embodiment of the invention, the contact carrier also has a rear extension. This extension has two windows to accommodate a locking latch on the terminal cap. The extension also has two protrusions to provide retention to two or more wire pairs after engagement of the terminal cap. The extension also has four other protrusions to minimize movement at the wire end, i.

The contacts must be installed prior to inserting the contact carrier into the connector housing. In the case of one embodiment of the present invention and when using the T568A standard pin / pair configuration, the R2 contact includes an insulator mobile terminal connected by a wire to a pair of plates connected to the modular outlet terminal. The R4 contact includes an insulator moving terminal connected by a wire to a plate connected to the modular outerlet terminal. The T4 contact includes an insulator moving terminal connected to the modular outlet terminal by a line. The T1 contact includes an insulator moving terminal connected by a wire to a plate connected to the modular outerlet terminal. The R1 contact includes an insulator moving terminal connected by a line to a plate connected to the modular outerlet terminal. The R3 contact includes an insulator moving terminal connected to the modular outerlet terminal by a line. The T3 contact includes an insulator moving terminal connected by a wire to a plate connected to the modular outerlet terminal. The T2 contact includes an insulator moving terminal connected by a wire to a pair of plates connected to the modular outerlet terminal.

One of the important features of the present invention is that one of the plates of the R2 contact is disposed opposite the plate of the R4 contact, and the other plate of the R2 contact is disposed opposite the plate of the R1 contact, between the opposing contacts. The dielectric plate (eg Mylar ™ or Kapton ™) is located. Thus, capacitive coupling is induced or added between the R2 and R4 contacts and between the R2 and R1 contacts. In addition, one of the plates of the T2 contact point is disposed opposite the dkfo of the plate of the T1 contact point, and the other plate of the T2 contact point is disposed below the plate of the T3 contact point, and a dielectric plate (for example, , Mylar ™ or Kapton ™). Thus, capacitive coupling is induced or added between the T2 and T1 contacts and between the T2 and T3 contacts.

Another important feature of the invention is that the plates of the contacts carry current. In particular, the flow of current through the contacts from the insulator moving terminal to the modular outerlet terminal and vice versa must be through the plates forming a capacitive coupling. According to this method of achieving a regulated positive capacitive coupling between selected contacts, the modular outlet can meet or exceed the Category 5 requirements, while at the same time resonating due to lack of signal reflection and / or signal balance The problem of crosstalk is excluded. In addition, even if the outlet connection portions are located in accordance with the standard configuration, the insulation displacement contacts are sequentially positioned, thereby excluding pair division in connection.

The method of achieving a regulated amount of capacitive coupling between selected contacts is an important feature of the present invention, in that the reactive imbalance between pairs and wire connectors caused by certain outletlet wiring methods is such that the plates and Compensated by the dielectric plates, the modular outerlet of the present invention can thus meet or exceed the requirements of category 5 described above without creating the problem of resonance crosstalk of the passive plates of the prior art. . The benefits of Category 5 are well known and will be readily appreciated by those skilled in the art. Most importantly, due to the bandwidth limitations of twisted pairs, significant cost savings are achieved in the past by using unshielded twisted pair wires where shielded coaxial or fiber optic cables were used.

Another important feature of the present invention is that although the modular outerlet connections are located according to a standard configuration, for example T568A, the insulation displacement connections are configured to improve the wiring connection. In particular, the terminal connections are in sequential form. In the standard T568A pin / pair system, the wire pairs T2 and R2 are not in sequential form and are divided from each other, so that at least these pairs must be partially twisted and wire 1 of pair 2 is pair 1 wire. And crosstalk, which causes additional crosstalk between the pairs and causes pair 2 to exhibit discontinuities in impedance at the ends. For high bandwidth applications, it is important to maintain the complete integrity of such twisted wire configurations in the case of the Elo Category 5 or emerging ATM standards. For this purpose, the twist loosening of the conductors should be minimized. According to the terminal configuration of the present invention, the above-mentioned problem is alleviated by eliminating the division of the pair at the time of connection.

The three-layer contact configuration according to the present invention not only maintains pair coupling force and consistent polarity during cable binding and terminal connection, but also inductive and capacitive response to ensure that the combined contact elements are integrated with the signal current paths. Provide balance It also provides parallel paths that allow the passage of current, which is proportional to the required coupling amount of the individual contact-to-contact method.

The terminal cap includes a terminal block portion in which wire retaining slots formed by a plurality of teeth are formed in a line. The T-shaped block extends from the front end of the terminal block portion, and the jacket holding block extends from the rear end of the terminal block portion on the opposite side. In another embodiment of the present invention, the terminal cap is fixed to the contact carrier by two locking latches. Four pairs of elastic tabs couple individual pairs into individual slots of the terminal cap, facilitating handling of the cable / terminal cap subassembly prior to coupling the terminal cap to the connector carrier.

In the case of conventional modular outlets using terminal caps, the method of installing the cable on the terminal cap is not effective. In such a conventional case, the user has to untwist each twisted pair, so that the cable can be installed in the terminal cap. Individual wires must also be stretched and aligned before being trimmed and trimmed if necessary. In this way, all the untwisted wires can be inserted simultaneously into the receiving holes of the terminal cap. However, this process is time consuming and inefficient when a large number of modular outlets have to be installed.

The terminal cap of the present invention reduces the cable preparation. The user simply disconnects the twisted pairs from the cable and inserts each twisted pair into the corresponding slot. Each twisted pair requires only partial twisting to allow individual wires to be placed in corresponding slots. After the wire is in place, only trimming will be needed.

Once the wires are inserted into the slots of the terminal cap and the cables are secured thereto, the wire portions extending beyond the slots are cut so that the ends of the wires are located on corresponding insulator moving terminals. Insert the blocks into the channel of the contact carrier, thus aligning the terminal caps in a row on the contact carrier and pushing downward until the insulator moving terminals move the insulator onto the wires and electrically connect with the conductive wire Terminal connection is made (group terminal connection). Preferably, the IDCs are also able to change the height to reduce the pressure required for the cap by making the terminal connection work in a short time.

The present invention also includes a shield that provides a single continuous path for connecting the entry shield structure to the discharge shield structure. This shield is particularly suitable for the second embodiment, but can also be applied to the first embodiment.

A resilient door structure is also included, which all provide a good seal for the opening.

The invention also includes an outlet door assembly that is maintainable in both an open position and a closed position. According to the present invention, there is a pair of mounting arms having inner extension protrusions received in the grooves to hold the door in the closed position and the open position. In one embodiment, the connector housing has an outwardly extending protrusion in the pair of grooves to determine the positions holding the protrusions of the door arms. In another embodiment, a door holder having groove pairs is used, in which one groove pair receives the protrusions of the door arm to hold the door in the closed position, and the other groove pair of the door arm holds the door in the open position. Accept the protrusions. In both of these embodiments, the door includes a channel for receiving a confirmation icon.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1, a modular outerlet having crosstalk reduction characteristics according to the prior art is shown by reference numeral 200. In FIG. This modular outerlet 200 has a connector housing 202 in which a contact carrier 204 for supporting a plurality of contacts 206 is received. The housing 202 is hingedly coupled with a terminal cover 208 for connecting a plurality of wires to one end of the contacts 206.

The contacts 206 are composed of eight contacts 210, 212, 214, 216, 218, 220, 222, and 224. The contact 210 comprises an insulator moving terminal 226 (ie pins 8, R4 according to T568A) connected by a plate 228 to the modular outerlet terminal 230. The contact 212 includes an insulator moving terminal 232 (ie, pins 7 and T4 according to T568A) connected to the modular outerlet terminal 236 by a line 234. The contact 214 includes an insulator moving terminal 238 (ie, pins 5 and T1 according to T568A) connected by the plate 240 to the modular outlet terminal 242. The contact 216 includes an insulator moving terminal 244 (ie, pins 4 and R1 according to T568A) connected by the plate 246 to the modular outerlet terminal 248. The contact 218 includes an insulator moving terminal 250 (ie, pins 2, R3 according to T568A) connected by a line 252 to the modular outerlet terminal 254. The contact 220 comprises an insulator moving terminal 256 (ie, pins 1, T3 according to T568A) connected by a plate 258 to the modular outlet terminal 260. The contact 222 includes an insulator moving terminal 262 (ie, pins 6 and R2 according to T568A) connected by a line 264 to the modular outerlet terminal 266. A line 268 extends from one side of the line 264 to the plate 270, and a line 272 extends from the other side of the line 264 to the plate 274. The contact 224 includes an insulator moving terminal 276 (ie, pins 3 and T2 according to T568A) connected to the modular outerlet terminal 280 by a line 278. Line 282 extends to plate 284 from one side of line 278, and line 286 extends to plate 288 from the other side of line 278.

The plate 228 of the contact 210 is disposed opposite the plate 274 of the contact 222, and the plate 246 of the contact 216 is disposed opposite the plate 270 of the contact 222. A dielectric plate 287 (Mylar ™ or Kapton ™) is located between these opposing contacts. Thus, contact 222 (i.e., pins 6 and R2 according to T568A), contact 226 (i.e., pins 8 and R4 according to T568A) and contact 216 (i.e., pins 4 and R1 according to T568A) Capacitive bonds are induced or added between. Further, the plate 240 of the contact 214 is disposed opposite the plate 288 of the contact 224, and the plate 258 of the contact 220 is opposite the plate 284 of the contact 224. And a dielectric plate 287 is positioned between the opposing contacts. Thus, contact 224 (ie pins 3 and T2 according to T568A), contact 214 (ie pins 5 and T1 according to T568A) and contact 220 (ie pins 1 and T3 according to T568A) Capacitive bonds are induced or added between.

Note that the plates are shunts connected to the signal carrier to allow passage of signals from the signal input to the signal output while preventing the passage of current. These passive capacitive plates have known problems such as resonance crosstalk and phenomena due to lack of signal reflection and / or signal balance. This contact configuration also requires the requirement to connect a pair of wire pairs, eg T568A, on contact points that are not adjacent to each other, and to make the positioning of tip and ring conductors inconsistent across all pairs. It has the additional disadvantage of being necessary.

Since the modular outerlet of the present invention does not use such passive plates, there is no problem of resonance crosstalk. 2A, 2B, 3A, 3B, 4A and 4B, the contacts with crosstalk reduction characteristics according to the present invention are shown by reference numeral 10. This contact 10 includes a connector housing 12 in which a contact carrier 18 for supporting a plurality of contacts 14 is accommodated. The housing 12 is coupled with a terminal cap 160 for connecting a plurality of wires to one end of the contact 14.

The connector housing 12 includes a front panel 20 in which a contact opening 22 of a standard is formed therein.

As shown in Figures 5A and 5B, the contacts 14 must be installed prior to inserting the contact carrier 18 into the connector housing 12. In the present embodiment, the contacts 14 are composed of eight contacts 102, 104, 106, 108, 110, 112, 114, and 116. The contact 102 connects the insulator moving terminal 118 (i.e., pins 6 and R2 according to T568A) connected by a line 120 to the plates 122 and 124 connected to the modular outlet terminal 126. Include. The contact 104 includes an insulator moving terminal 128 (ie, pins 8 and R4 according to T568A) connected by a line 130 to a plate 132 connected to the modular outerlet terminal 134.

Include. In general, the contacts are held in position as required by conventional means such as ultrasonic welding, swaging, stacking, adhesives and the like.

One of the important features of the present invention is that the plate 122 of the contact 102 is disposed opposite the plate 132 of the contact 104, and the plate 124 of the contact 102 is the plate of the contact 110. Disposed opposite 154, between which the dielectric contacts 182 (eg, Mylar ™ or Kapton ™) are located. Thus, between contact 102 (ie pin 6, R2 according to T568A) and contact 104 (ie pin 8, R4 according to T568A) and contact 102 (ie pin 6, R2 according to T568A). ) And a capacitive coupling is induced or added between contact 110 (ie pins 4, R1 according to T568A). Further, the plate 176 of the contact 116 is disposed opposite the plate 146 of the contact 108, and the plate 178 of the contact 116 is below the plate 168 of the contact 114. Is disposed opposite the dielectric plates 184 (eg, Mylar ™ or Kapton ™) between the opposing contacts. Thus, between contact 116 (ie pins 3 and T2 according to T568A) and contact 108 (ie pins 5 and T1 according to T568A) and contact 116 (ie pins 3 and T2 according to T568A). And a capacitive coupling is induced or added between contact 114 (ie, pins 1, T3 according to T568A).

Another important feature of the present invention is that the plates 122 (, 124, 132, 146, 154, 168, 176, and 178 carry current. The flow of current through the contacts from the insulator moving terminal to the modular outerlet terminal and vice versa must be through the plates forming a capacitive coupling.

This method of achieving a regulated amount of capacitive coupling between selected contacts is an important feature of the present invention, in that the reactive imbalance between pairs and wire connectors caused by certain outletlet wiring methods is not affected by the plates and Compensated by the dielectric plates, the modular outerlet of the present invention can thus meet or exceed the requirements of category 5 described above without creating the problem of resonance crosstalk of passive plates of the prior art. The benefits of Category 5 are well known and will be readily appreciated by those skilled in the art. Most importantly, due to the bandwidth limitations of twisted pairs, significant cost savings are achieved in the past by using unshielded twisted pair wires where shielded coaxial or fiber optic cables were used.

As shown in Figs. 6A and 6B, the contact 102 has a terminal 126 located in the slot 64f, a line 120 located in the slot 86f, and a terminal 118 opening the opening 88f. It is installed on the contact carrier 18 in the form of being inserted through. The contact 104 has a contact carrier 18 in such a way that the terminal 134 is located in the slot 64h, the line 130 is located in the slot 86g, and the terminal 128 is inserted through the opening 88g. Installed on the The contact 106 is a contact carrier 18 in such a way that the terminal 140 is located in the slot 64g, the line 138 is located in the slot 86h, and the terminal 136 is inserted through the opening 88h.

Installed on the The contact 112 has a contact carrier 18 in such a way that the terminal 162 is located in the slot 64d, the line 160 is located in the slot 86a, and the terminal 158 is inserted through the opening 88a. Installed on the Contact 114 has contact carrier 18 in such a way that terminal 170 is located in slot 64a, line 166 is located in slot 86b, and terminal 164 is inserted through opening 88b.

Installed on the

Another important feature of the present invention is that although the modular outerlet terminals are located according to a standard configuration, for example T568A, the insulator mobile terminals are configured to improve the wiring connection. In particular, the sequential terminals 164 and 158 correspond to T3 and R3, respectively, and the sequential terminals 142 and 150 correspond to T1 and R1, respectively, and the sequential terminals 172 and 118 correspond to T2, Corresponding to R2, respectively, and the sequential terminals 136 and 128 correspond to T4 and R4, respectively. For terminals T568A, wire pairs T2 and R2 are not in sequential form and are divided from each other, so that at least these pairs must be partially twisted at the ends. For high bandwidth applications it is important to maintain the complete integrity of the twisted wire configuration as described above, for example in the case of category 5 or emerging ATM standards. For this purpose, the twist loosening of the conductor should be minimized. According to the terminal scheme of the present invention, the above problem is alleviated by eliminating the division of the pair at the time of connection.

As shown in FIGS. 7A and 7B, the terminal cap 16 includes a terminal block portion 182 having a row of wire retaining slots 188 formed by a number of teeth 186. The teeth 186 include an inner flange 188 that grips the wire by an insulator, which has a tapered end 190 to facilitate entry of the wire. The T-shaped block 192 extends from the front end of the terminal block portion 182, and the jacket retaining block 194 extends from the rear end of the terminal block portion 182 on the opposite side. Block 194 includes an arcuate recess 196 for receiving a jacket of cable to be connected, and holes 198 and 200 formed therethrough. The cable to be connected is connected to the terminal block portion 182 by inserting a cable tie (not shown) through one of the holes and through the other hole around the cable as is well known and then joining the cable tie. It will be fixed. For example, according to the T568A criterion and the improved terminal configuration of the present invention, a wire T3 is inserted into the slot 184a, a wire R3 is inserted into the slot 184b, a wire R1 is inserted into the slot 184d, and the slot Wire T1 is inserted into 184e, wire T2 is inserted into slot 184c, wire R2 is inserted into slot 184f, wire T4 is inserted into slot 184g, and wire R4 is inserted into slot 184h.

Once the wires are inserted into the slots of the terminal cap and the cables are secured thereto, the wire portions extending beyond the slots are cut so that the ends of the wires are located on corresponding insulator moving terminals. Insert the blocks 1920 into the channel 74 of the contact carrier 18, thus aligning the terminal caps in a row on the contact carrier, and allowing the insulator moving terminals to move the insulator onto the wires to electrically connect with the conductive wire. Pushing downward until a terminal connection of the wires is made (collective terminal connection) The terminal cap 16 is formed on the contact carrier 18 by holding surfaces 200 and corresponding inclined surfaces 202. Retaining surfaces 200 are engaged in the holes 30 of the connector housing 12 on the upper surfaces of the projections formed by the surfaces 90, 92 of the contact carrier 18. Thus, each hole 30 acts to retain or engage the terminal cap 16 by the retaining projections 92 and the contact carriers 18 by the retaining surfaces 200.

Edges of surfaces 344 and 346 are shaved. The insert 43 is inserted into the slot 42 of the connector housing 12 to be held by friction. Insert 43 can form marks or color code on its surfaces 344, 346. In one example, computer terminal 345 is shown on surface 344 (FIG. 8A) and telephone 347 is shown on surface 346 (FIG. 8B). Certain indication symbols or terms may be integrally formed or imprinted on these surfaces depending upon the particular application of the modular outlet.

In Fig. 9 two modular outlets 10, 10 'are shown, which are provided in corresponding openings 352, 354 of the wall plate 356. Figs. The slots 44, 58 of each modular outlet accommodate the corresponding edges of the wallboard in the openings. As clearly shown in the figures, the modular outerlets provide gravity transfer thereto. The advantage of this gravity transfer is well known and is described, for example, in US Pat. No. 5,362,254 to Siemon et al., Which is incorporated herein by reference.

The contact 110 'is an insulator moving terminal 150' (i.e. pins 4, R1 according to T568A) connected by a line 152 'to a plate 154' connected to a modular outerlet terminal 156 '. It includes. The contact 112 'includes an insulator moving terminal 158' (i.e., pins 2, R3 according to T568A) connected by a line 160 'to the modular outerlet terminal 162'. The contact 114 'is an insulator moving terminal 164' (i.e. pins 1, T3 according to T568A) connected by a line 166 'to a plate 168' connected to a modular outlet terminal 170 '. It includes. The contact 116 'is connected to the plates 176' and 178 'connected to the modular outlet terminal 180' by an insulator moving terminal 172 '(i.e. according to T568A) Pins 3 and T2).

One of the important features of the present invention is that the plate 122 'of the contact 102' is disposed opposite the plate 132 'of the contact 104', and the plate 124 'of the contact 102' is It is disposed opposite the plate 154 'of the contact 110', with a dielectric plate (for example, Mylar ™ or Kapton ™) located between the opposing contacts. Thus, between contact 102 '(i.e., pin 6, R2 according to T568A) and contact 104' (i.e., pin 8, R4 according to T568A) and contact 102 '(i.e., pin according to T568A). 6, R2) and a capacitive coupling is induced or added between the contact 110 '(i.e., pins 4, R1 according to T568A). In addition, the plate 176 'of the contact 116' is disposed opposite the plate 146 'of the contact 108', and the plate 178 'of the contact 116' is the contact 114 '. Is disposed opposite the plate 168 ′ of the dielectric plate, and a dielectric plate (eg, Mylar ™ or Kapton ™) is positioned between the opposing contacts. Thus, between contact 116 '(i.e., pins 3 and T2 according to T568A) and contact 108' (i.e., pins 5 and T1 according to T568A) and contact 116 '(i.e., pin 3 according to T568A). , T2) and a capacitive coupling is induced or added between the contact 114 '(i.e., pins 1, T3 according to T568A).

In this embodiment, an important feature of the present invention is that the insulator mobile terminals are configured to improve the wiring connection, although the modular outerlet terminals are located in accordance with the standard configuration, for example T568A. In particular, the sequential terminals 158 'and 164' correspond to R3 and T3, respectively, and the sequential terminals 150 'and 142' respectively correspond to R1 and T1, and the sequential terminals 118 'and ( 172 'corresponds to R2 and T2, respectively, and sequential terminals 128' and 136 'correspond to R4 and T4, respectively. For terminals T568A, wire pairs T2 and R2 are not in sequential form and are divided from each other, so that at least these pairs must be partially twisted at the ends. For high bandwidth applications it is important to maintain the complete integrity of such twisted wire configurations as, for example, Category 5 or emerging ATM standards. For this purpose, the twist loosening of the conductor should be minimized. According to the terminal configuration of the present invention, the aforementioned problem is alleviated by eliminating the division of the pair at the time of terminal connection. Moreover, in the case of the present embodiment, not only the corresponding T-R pairs are kept together, but also the alternating T-R order for all four pairs at the input stage is kept consistent. The input order is R3 T3 R1 T1 R2 T2 R4 T4, which provides the advantage that T1 and T2 are not located adjacent to each other. These wires are all white in color and therefore can cause confusion during installation if they are adjacent to each other. This is obviously an advantage.

11A-15B show another embodiment of a mechanical structure for supporting the electronic elements of the modular jack 410 of the present invention. The connector housing 412 shown here is configured to receive a contact carrier 418 that supports a plurality of contacts 414. A terminal cap 416 is coupled to the carrier 418 to terminally connect, protect, and mechanically secure a plurality of wires at one end of the contacts 414.

The connector housing 412 includes a front panel 420 having a modular jack opening 422 formed therein. Rearward from the panel 420, a pair of side panels 424 and 426 extend parallel to each other, which have mounting holes 428 and 430, respectively. have. The upper panel 432 also extends rearward from the panel 420 to connect the upper edges of the panels 424 and 426. The panel 432 includes inclined members 434a and 434b, which increase the thickness of the panel 432 and have a pair of protrusions 436 formed at the ends thereof. The members 434 and the projections 436 together form a slot 442 that slidably receives the icon or insert 43 (the icons are illustrated in FIGS. 8A and 8B related to the description of the above-described embodiment). The same applies to this embodiment). At the rear of the slot 442 is a panel receiving slot 444, which is located in the rear portion of the end member 434b, the cutout 446 (formed on the cap 416 described later). And by removing the panel material from the side panels 424, 426. The housing 412 also includes a lower panel 452 located opposite the upper panel 432 and extending rearward of the panel 420, the front end of which is curved upward. From the rear end of the panel 452, the elastic panel 454 extends along the outer shape of the panel 452. A panel receiving slot 456 is formed at the front end of panel 454, which slot 456 is adapted to engage a wall panel, plate or similar member (a representative plate is shown in FIG. 9). A nub 455 is formed upward from the front edge of the member 454 to guide the insertion of the door 870 (this will be described later). In addition, ribs 453 are formed upward from the member 454, which ribs 453 are engaged with the doors to support the doors.

As shown in Figures 13A, 13B, 14A, and 14B, the contact carrier 418 includes a generally L-shaped front member 462 that fits into a standard modular outlet, the interior of which is a contact ( It has a number of slots 464 for receiving 414. Slots 464 are formed in the partial channel 470 formed at the front end of the lower leg 468 of the front member 462 and at the front face of the upper leg 472 of the front member 462. The second channel 474 is formed on the rear surface of the upper leg 472. Channel 474 is formed by box-shaped extensions 469 having edges 471 cut on the upper edges, which extensions 469 also include housing 412 upon assembly of the housing and carrier 418. Grooves 473 located in the same space as the panel receiving slot 444 therein. The front end of the lower leg 468 is inclined to cooperate with the curved front end of the panel 452 when the contact carrier 418 is inserted into the connector housing 412. Arms 476 and 478 are provided to hold the contact carrier 418 inside the connector housing 412, which arms 476 and 478 are provided within the connector housing 412. 418 has an inclined surface 480 and retaining edge 482 that facilitates insertion of 418 from the rear end, respectively. Retention edges 482 are coupled to and received in holes 428 of side panels 424 and 426. The terminal block portion 484 extends rearward from the lower end of the leg portion 472, and a plurality of slots 486 are formed in the lower portion of the terminal block portion 484 to accommodate the contact point 414. . The lower portion of the terminal block portion 484 itself has three distinct faces formed at three different heights for positioning the contacts. The back faces are shown by reference numerals 485a, 485b and 485c in Figs. 14B and 14C. Each of these faces allows for the positioning of the required contact. In addition, the faces are integrally molded to the carrier itself, thereby providing mechanical stability for the individual contacts located on each of the faces. It should be understood that the slot 464 also includes faces 485a, 486b and 486c formed at three different heights to correspond to the faces shown in Figure 14C. Each slot 486 is connected to an opening 488 extending through the block portion 484 through which the corresponding contact 414 passes. In each of the side portions 494 and 496 of the block portion 484, an inclined surface 490 having a retaining protrusion 492 is formed. In addition, a recessed portion 498 is formed between the block portion 484 and the lower extension portion 500 of the lower leg portion 468, and the recessed portion 498 includes a contact 414 provided in the contact carrier 418. The parts of the field are housed.

A cable trap 700 extends behind block 484, which includes sidewalls 702. The sidewalls 702 also have a cutting edge 704 to hold a terminal cap, which will be described later. The body 706 of the trap 700, located between the side walls 702, includes a plurality of, preferably four, protrusions 708 facing toward its rear portion. These protrusions engage the tabs on the terminal cap to support the tabs, thereby preventing them from breaking when the cable is pulled. In addition, retention of the wire is achieved by the protrusions 710. These protrusions provide light retention or strain relief only for the two center pairs, as will be appreciated by those skilled in the art. However, such light strain relief is not necessary in the present invention.

What has been described above in connection with the above-described members are various features of the terminal cap 416 of this embodiment. As discussed above, the protrusions 708 are located just below the tabs 712 of the cap 416. It should be noted here that the tabs 712 are configured to bend to allow the passage of twisted pairs so that they may break during rough handling. The projections 708 support the tabs 712 when the cap 416 is coupled to the carrier 418 to mitigate this possibility of breakage. The tab 712 itself extends from walls 714 extending downward from the bottom surface 716 of the cap 416. The discontinuous portions of the lower surface 716 together with the latch 718, the support tab 728 and the center wall 730 form a groove 732 as shown in FIG. 15A. Each of the four grooves 732 is configured to allow the corresponding twisted passes to pass through the plurality of wire retaining slots 584 formed by the teeth 568. Each tooth 568 includes a retaining head 587 that is narrowed at the end side and widened as it approaches the body as shown. This configuration provides for each untwisted wire a passage that is wider than the conductor itself but narrower than the outer dimension of the insulator. In this way, a predetermined retention effect is provided. Note that each twist pair is inclined upwardly from the groove 732 to the second lower surface 734 along the inclined surface 733 so as to facilitate the entry of the wire into each slot 584. The second bottom surface 734 supports the separating protrusions 736 and also provides an IDC receiving portion 738 for receiving IDCs pressed on individual wires. The individual wires are not twisted until they extend beyond the protrusion 736, thus minimizing the untwisted portion. The protrusions 736 are four and serve to separate four passages for each twisted pair. If the wires are bound in corresponding slots in the untwisted state, the wires are located above the IDC receptacle 738, which is then placed over the required IDCs extending upwards from the contact carrier 418. It is located.

The contacts of this embodiment provide the same advantages as the above-described embodiments, and are arranged in much the same way.

It should be noted here that the advantage of the configuration of the present invention is that the collective terminal connection can be easily made to the extent that the pressure required for terminal connection of the wires can be reduced. This reduction in pressure is caused by staggered heights of the IDCs. When the height is staggered, several wires may be connected at the same time while supporting the terminal cap 416 to be coupled to the jack 410.

Once the wires are inserted into the slots of the terminal cap as described above, the wire portions extending beyond the slot are cut so that the ends of the wires are terminally connected on the corresponding insulator moving terminals. Insert the block 592 into the channel 474 of the contact carrier 418, thus aligning the terminal cap 416 in a row on the contact carrier 418, wherein the insulator moving terminals move the insulator onto the wires. The terminal connection of the wires is made (ie, collective terminal connection) by pushing downward until it is electrically connected to the conductive wire. The terminal cap 416 is held on the contact carrier 418 by latch lips 740, which latches of the latch lip can later be removed by conventional means, if necessary.

Mounting on the insert is the same as described above.

In Fig. 18, six modular outerlets 10a to 10f are shown installed in the corresponding openings 353 and 355 of the wall plate 357 (laterally stacked). Slots 444 and 458 of each modular outlet receive corresponding edges of the wallboard in the openings. As is clearly shown in this figure, the modular outlets provide gravity transfer thereto. The advantage of this gravity transfer is well known and is described, for example, in US Pat. No. 5,362,254 to Siemon et al., Which is incorporated herein by reference. It should be noted that the jacks of the present invention can be inserted both before and after the plate to facilitate installation.

As in the other embodiments described above, an important feature of the present invention is that the insulator mobile terminals are configured to improve wiring connection, although the modular outerlet terminals are located in accordance with a standard configuration, for example T568A.

What is described in relation to this outlet is also an elastic door for a modular plug opening, in which Figure 16A shows the entire assembly with the door 870 in place, and in Figure 16B the door has been removed for a closer look.

As shown in Figures 17A-17D, the door 870 includes a plate 872 having a pull tab 874 extending from one edge and an opening plug 876 protruding from the rear surface. . A hinge coupling member 878 is located on the plate opposite the tab, which may be coupled between the lower panel of the housing 418 and the elastic member. Hinge engagement member 878 includes a narrow band 880 extending immediately adjacent plate 872 across the member 878 laterally. The band 880 acts to facilitate the operation of the door 870. The member 878 also includes a wedge 882 connected to the band 880, which is in communication with an area formed between the lower panel 452 and the elastic member 454. Grooves 881 are formed on the member 454 to join the ribs 453. In addition, a channel 883 is provided to align the member 878 in line with the nub 455 upon insertion. The door 870 is made of deformable material, preferably neoprene material. The door should only be inserted into the housing after the outletlet is inserted into the wall plate. Otherwise, the resistance of the door prevents the elastic member 454 from deforming enough to insert the outletlet into the plate.

19, a shield 760 is shown with an excerpt from the contact carrier 418 illustrated herein. This shield can be used with all of the jacks described herein in conjunction with the required connections if necessary. This shield provides a single continuous low impedance connection for the entry and exit cable shields, not shown. As will be appreciated by those skilled in the art, low impedance paths eliminate the current transfer disadvantages of multiple connections and are therefore high impedance paths.

The shield of the present invention includes a pair of fingers 762 extending from the frame 764, which are the contact points for the shield contacts on the plug to be inserted into the jack of the present invention. To make a secure connection, the ends 766 of the finger include inwardly projecting bends, which act to tighten subsequent connections. The frame 764 also includes a ground tab 768 that is optionally connected to a ground housing, not shown. The tab 768 is configured to be used for a standard female terminal (not shown). As another example, if grounding is needed, an upright portion 770 having an inclined end 772 extends from the upper edge of frame 764 to provide grounding on the ground faceplate. In this case, the ends 772 are seated in the notches 473 on the carrier 418 and contact the face plate when the jack is inserted into the carrier 418.

The rear edge of the frame 764 supports the rear extension member 774 extending rearward to the end plate 776. In order to provide sufficient space for the contact carrier 418 between the members 774 in engagement, each member includes two bending zones. The spacing between the members 774 in the front bend area 778 is wide, and the spacing in the back bend area 780 is narrowed to approximately the same dimensions as the frame 764. Plate 776 forms a contact area for the entry cable shield.

Fig. 20 shows a partial exploded view of the present invention with the shield positioned. In this illustrated state, it can be seen that the end 772 is located in the notch 473. A closer look at the drawings will fully understand the bonding state of the shield 760 to the carrier 418. 21 and 22 show the assembled state of the entire outlet.

The upper panel 832 includes inclined stops 834A and 834B that are inclined toward each other, the inclined stops having opposing stop surfaces forming a panel receiving slot 844. The slot 844 is spaced much narrower than the gap of the slot 444 relative to the panel 420 in the above-described embodiment because the outlet 810 does not have the purpose of providing gravity transfer. It is located close to.

The lower panel 852 is curved upward to meet the front panel 820 similarly to the panel 452, but an icon groove 851A is formed adjacent to the interface between the panels 852 and 820. The icon groove is coplanar with the icon groove 851B located on the elastic member 854 extending from the lower panel 852. Like the elastic member 454, the member 854 has a panel receiving slot 856. As will be appreciated by those skilled in the art, once the panel receiving slots 844, 856 are combined with the panel, upon entry of the icon 43 into the icon grooves 851A, 851B. The bending of the member 854 is prevented, thereby causing the outerlet to be locked in the panel. In this state, the outlet cannot be detached without removing the icon.

It should be understood here that depending on whether or not the shielding is on or off, it is determined in each embodiment whether or not it is necessary or not to enable the stacking of multiple outlets of industrial size in a single opening laterally. to be. Thereby, space efficiency is provided, as a result of which the aesthetic effect of wall mounting of multiple outlets is increased and the requirements of the high outletlet density required in some cases are met. The wallboard opening may have a width that can accommodate the required number of outletlets.

In addition, all of the above-described embodiments are configured to be able to couple to the wall plate from both the front and rear directions, thereby increasing the connection option, eliminating the common disadvantages associated with the connection from the rear of the plate, and only having to be fixed to the wall. There is only a requirement that all cables be "filled" into the junction box for the plate.
